Subject: [ruby-core:72897] [Ruby trunk - Feature #11999] [Open] MatchData#to_h to get a Hash from named captures

Issue #11999 has been reported by Shota Fukumori.

Feature #11999: MatchData#to_h to get a Hash from named captures

class MatchData
  def to_h
    self.names.map { |n| [n, self[n]] }.to_h
  end
end

p '12'.match(/(?<a>.)(?<b>.)(?<c>.)?/).to_h #=> {"a"=>"1", "b"=>"2", "c"=>nil}
~~~

Sometimes I want to get a Hash from named capture, but currently I have to use #names + #captures. How about adding MatchData#to_h for convenience way?
